Mechanical sand is the key to the healthy development of the sand and gravel industry

Sand and stone are the basic and indispensable building materials in engineering construction. The Party Central Committee and The State Council attach great importance to the healthy and orderly development of the sand and gravel industry. In order to stabilize the supply of sand and gravel market, maintain the overall stability of prices, and promote the healthy and orderly development of the industry, with the consent of The State Council, on March 25, the National Development and Reform Commission and other fifteen departments and units jointly issued the Guiding Opinions on Promoting the Healthy and Orderly Development of the sand and gravel Industry.

The gap in the sand and stone industry is as high as 80%

Under the impact of the epidemic, since the resumption of work across the country after the Spring Festival, many provinces have issued 2020 project investment plans. As of March 20, the total investment of 22,000 projects announced by 25 provinces and municipalities, including Beijing, Hebei, Shanghai, Guangdong, Sichuan and Ningxia, reached 49.6 trillion yuan, of which the total planned investment in 2020 was 7.6 trillion yuan. There are increasingly clear signs that big infrastructure is becoming a new driving force for the economy.

Crawler mobile impact crushing station low capacity, less money how to do?

Because of its simple operation, convenient transfer, high cost performance, high output, good product particle shape, and environmental protection dust treatment device in line with the relevant requirements of the state for environmental protection, the caterpillar mobile impact crushing station has been widely popular in recent years. It is more common to apply to the initial processing of solid waste resources such as construction waste regeneration, the past caterpillar mobile crushing station is usually combined with caterpillar mobile screening station, and some enterprises have developed a new caterpillar mobile crushing and screening machine, which can not only produce, but also effectively reduce the user's purchase cost. Without loss, it is an alternative for the primary processing of solid waste resources such as construction waste.

The mobile gravel crusher for construction waste promotes the green development of cities

With the rapid development of cities, the disposal of construction waste generated from infrastructure construction or house demolition has become a highly concerned issue at present. Meanwhile, mobile stone crushers for handling construction waste in the crushing industry have also ushered in huge development opportunities. Mobile construction waste is used to handle surface soil and various other materials. Separation of viscous concrete aggregates; Construction and blasting industry; Screening after crushing; The quarrying industry. Recycling of construction waste. Such as the crushing in the recycling of concrete during house demolition and road construction; Aggregate crushing in asphalt and concrete mixing plants.

How to choose a crawler-type mobile crushing station for hard rock crushing?

In the processing of machine-made sand and gravel, it is very important to master the properties of the raw material rocks, such as the physical and mechanical properties, mineral composition, chemical composition of the rocks, and the processing performance index of the rocks. It is mainly necessary to understand the crushing energy index and erosion index, which serve as important reference indicators for the initial equipment selection, subsequent production and processing, and maintenance of sand and gravel equipment. In simple terms, it refers to the breakability and abrasiveness in the rock processing performance.
